These two pictures show sunspots on the Sun in 2001 (top) and 2003 (bottom). Sunspots only form near the Sun's equator and are never seen near the Sun's poles.

The Sun is not a solid object. It is giant ball of gas and plasma. Some parts of the Sun rotate more slowly than other parts. At the equator, the Sun spins pretty fast. It takes 25 days to turn all the way around. It turns more slowly at the poles. The poles take 34 days to spin around once.

The Sun's atmosphere at the poles is also different from the atmosphere above the Sun's equator. The corona, part of the Sun's atmosphere, sticks out further from the Sun's surface near the equator. The corona doesn't stick out as far above the poles. The solar wind is also different at the poles. It "blows" much faster above the poles than it does above the Sun's equator.
